Eccentric millionaire Truman Capote invites six of the world’s greatest detectives to his mansion for “dinner and a murder.” When the sleuths (Peter Sellers, David Niven, Maggie Smith, James Coco, Peter Falk and Elsa Lanchester) arrive and discover that the host is the apparent victim, they attempt to solve the puzzle and survive the evening themselves. Neil Simon’s dazzling script parodies virtually all the conventions of the murder mystery while throwing in enough red herrings to keep the audience guessing until the very end. With Alec Guinness.
